CEMENT INTERLOCKING PLATE.

Specification of Letters Patent.

Patented June 20, 1922.

Application filed March 31, 1919. Serial No. 286,303.

To all whom it may concern:

Be it known that Or'ro FABER, citizen of Germany, residing at La Porte, in the county of Harris and State of Texas, has invented new and useful Improvements in Cement Interlocking Plates, of which the following" is a specification.

The purpose of the invention is to provide a cement plate or slab formed with means for interlocking it with others of the same kind so that a hollow wall may be built with the inner section spaced from the outer section. The plate is of such a character that those comprising the inner section of the wall have their points broken, or staggered with respect to those comprising the outer section. The plate in use is deslgned to stand upright-that is, it is placed in the wall of which it is a part so that it stands vertical in the direction of its length and it is intended that the plates shall be made of a length suitable to the height of the wall which they are to form.

The invention is illustrated and described in a specific embodiment to which it is not to be restricted. The right is reserved to make such changes or alterations as the actual reduction to practice may suggest in so far as such changes or alterations are compatible in spirit with the annexed claim.

In the accompanying drawings:

Figure 1 is a horizontal sectional view through a corner wall constructed with the improved plates.

Figure 2 is a horizontal through one of the plates.

Referring to the drawings,

sectional View the invention is shown as comprising a concrete slab or plate 8 which has the flange portions 9, these flange portions 9 on their outer faces being provided with the semicircular depressions or grooves 10 but the plates 8 intermediate between the flange portions are provided with a third longitudinal flange portion 11 whose opposite faces are at right angles to the outer face of the plate 8, and formed each with a depression 10, and therefore parallel with the outer faces of the flange portions 9. These plates 8 and their flange ortions 9 and 11, are provided with the remforcements 3 and 4. In assembling the plates 8 to form a wall, as shown in Fig.

1, a pluralityof upstanding plates is employed to form the outer wall and the inner wall is similarly formed, the two walls having their flange portions oppositely disposed, but the intermediate flanges of the outside plates stand between the edge flanges 9 of the inside plates and similarly the intermediate flanges of the inside plates stand between the edge flanges of the outside plates, thus positioning each depression 10 on each outside plate opposite a depression 10 on each inside plate. The double row of plates is set upon a suitable foundation and when placed as shown in Figure 1, the spaces between the inner and outer walls are filled with a strong cement mortar to a height of about one and one-half inches, the mortar resting upon the foundation and adhering to the inner faces of the body portions of the plates and the inner faces of the end flanges thereof, thus securing the plates to the foundation. The securing of the plates togetl er is then completed by pouring a thin cement mortar in the joints or keys comprising the facing semi-circular depressions 9 and 10 in adjacent flangeportions.

With the construction shown in Fig. 1 the inner and outer walls are positively interlocked and this arrangement is provided to suit the needs of heavy construction.

The invention having beei described, what is claimed as new and useful is:

I A wall structure consisting of inner and outer interlocking wall elements of which each comprises a plurality of plates consisting of slab like bodies formed at each longitudinal edge with flange portions extending the full lengths of the bodies, the latter be1ng further formed with intermediate flange portlons extending the full length of the body flanges of adjacent plates ofthe opposite wall, the extremities of the intermediate flange portions being exposed at the outer face of the opposite wall. the adjoining faces of adjacent flanges being formed with intermediately disposed seats for the reception of keys. I

In testimony whereof he afiixes his signature.
